For many people in the content industry its a way of life. The wheeling and dealing, the insider club, the exclusivity, once you get there you have a small group surrounding you. A group that you tend to stick with. That shares the same values, have their own dialect, and has the same faith in the way things have always been done.
Groups like this tend to strike out at anything that threatens their way of life. Religious, Political, and Social groups all do this. They rationalize their actions and believe anything, no matter how logically incorrect, to support their point of view. In order to maintain the coherence of the group they always find another group or a concept to demonize. For the longest time it was any sort of change, now their demon is the internet and they are using Google as its face.
If large enough these groups become stuck in a perpetual denial, anger, bargaining loop. The loop is driven by a meme gaining strength and giving hope, running its course through the group. Each time through the loop they push further, each time thinking this will fix the problem. The content industry has been doing this for 30 years now. The end result is the copyright in its modern form.
